Bug#402164: #402164: segfault in cyrus imapd using nss-ldap, libsasl and gssapi

[Mark Ellis]

Package: libsasl2-2
Version: 2.1.22.dfsg1-8
Followup-For: Bug #402164


I believe I have found another reference to this at http://www.mail-archive.com/cyrus-devel@lists.andrew.cmu.edu/msg00020.html

The short version, is that gss_mutex is set to (void *)1 by the default sasl_mutex_alloc in lib/common.c. At some point libldap then registers its own mutex 
callbacks, and attempts to lock gss_mutex, resulting in the segfault.

The above reference provides a temporary fix. Not knowing the implications of sasl internals i'm not sure where this needs to be fixed.
